Epilepsy in multiple sclerosis as a network disease

This is a review paper, essentially a commentary with summary of literature that actualizes the problem of epilepsy in patients with multiple sclerosis. There is a bidirectional relation between multiple sclerosis and epilepsy. A possible associate pathophysiological pathway is considered. In multiple sclerosis, a combination of gray matter involvement and inflammation could influence epileptogenesis. Patients with multiple sclerosis have individual profiles and an inter-individual variability of epileptogenicity. No treatment guidelines have been specified for these patients. We postulate that an epileptic manifestation means a relapse or an aggravation of the inflammatory process. In this condition, over time, this symptom could integrate into the Expanded Disability Status Scale. Epileptogenesis is an active process and an interesting question is if disease-modifying therapy in multiple sclerosis can prevent, or mitigate, epilepsy. In light of the latest knowledge of the inflammatory process in epilepsy, the possibility of preventing epileptogenesis with actual treatment of MS is emphasized. We would argue that it is a strong argument for starting treatment quicker for both diseases. Over the last few years, the concepts of epilepsy have completely changed. The model of epilepsy in multiple sclerosis can currently be regarded as a network disease and this new concept can have a highly significant clinical impact.
